When the compiler says "code has no effect", it is saying that it does not matter if the code is executed or not - the end result will be the same. The compiler, if in optimizing mode, can and should delete the code. An example of code that has no effect is a = a;
A function is a self contained block of code that perform of particular task.
You can't. If you have no main function, then there is no entry point to your code and it cannot be executed. Code without a main function is essentially a library. In MS Windows, GUI mode, you don't have to have main function. (WinMain is used instead).
You could just define the whole function before it is called, like this:void do_nothing(){}main(){do_nothing();}but if you define the function after it is called, the compiler will arrive at the function's calling before its actual definition. If you prototype your function earlier in the code than the function's call, the compiler will look for the function first.Hope I was able to help.
we can do this using of javascript. you can use this following code: <input type=button value="button" onClick=onclick_function()> here onclick_function() is a function which is called by javascript on clicking the button. javascript code is as follows: <script language="javascript" type="text/javascript"> // your code for onclick_function() function onclick_function(){ alert("Welcome to javascript"); } </script>

Register the function(s) containing the code with atexit.

In a computer OS translates mecheane language like bainary code (0010)etc into human language like english so that we can understand it.
If sizeof were a function, the following code would work (you can try with any other function):printf ("Function sizeof is located at %p", sizeof);On the other hand, the following code wouldn't work, as functions don't accept a type as parameter:size_t intsize= sizeof (int);
Assembly language is the programming language that always has a one to one correspondence for a line of code in that language and a line of code in machine language
Try and code simple things like alert statements, function calling on click event of form submit, function declaration and variable assignment. Bottom line is code and then only you will learn any programming language.
The language code for the keyword "no" is "Norwegian."
.net is technology in which we can design application as we wish and can write code in c# or vb anyone language
The function keyword in PHP allows users to define functions beyond those built into the language, like so: function isFour ($number) { return $number == 4; }Functions in any language, including PHP, allow the developer to re-use their code. Without functions all of the code required to do the simplest of tasks must be re-written constantly; but with functions you must only write the code once and then call it whenever needed.
The assembler is translator which converts assembly language code into machine language code.
A function is a subroutine that can be called from several places (re-usable code). Functions can accept arguments (or parameters) so that they can be more generalised and can also return a value to the caller.
